I have not run fsck to repair with the previous disk this when wrong, so 
   I will buy a spare 750 GB disk today, and make a dd image from the 
one disk to the other.

I have seen the usb bus reset errors before but I cant put my finger on 
the broken part. I have now been copying data from one usb disk to an 
other usb disk without any usb error messages and this is a 4 hour transfer.

No RAID setup, but i am planning a software raid setup soon.
